We design and build software products, data platforms, AI systems and optimisation models for organisations that need technology they can rely on every day.
Relevant professional experience
We take on work where code, data, models and infrastructure need to operate together. We begin by defining the outcome, the users and the constraints, then design around them.
Data engineering
We combine data sources, business rules and operating workflows in an architecture that makes quality, lineage, ownership and cost visible from the start.
Lakehouse architectures · regulated environments · global supply chains
AI and machine learning
We develop predictive and generative AI around the data, permissions and people involved. Evaluation, deployment, monitoring, cost and ownership are part of the work, not an afterthought.
LLM applications · predictive models · document retrieval
Mathematical optimisation
We model planning, allocation, routing and scheduling around the constraints that apply in practice. Optimisation and simulation then support decisions people can explain and act on.
Routing · resource allocation · planning under multiple constraints
Scientific computing
We turn experimental workflows into maintainable software without losing scientific rigour. Data, parameters and results remain traceable, repeatable and ready for further analysis.
Genomics platforms · oncology data · published biomedical research
Custom software
We build portals, applications and services around the way each organisation works. Product, backend and data are designed together to simplify operations and reduce manual work.
Operational portals · public-sector processes · backend and data services
Selected work across enterprise platforms, regulated banking, consumer goods, global digital services, genomics and oncology. In every case, the technology had to withstand daily use and deliver a practical result.
Selected experience
01/05
Each project starts by agreeing a concrete outcome and understanding who needs it, what constraints apply and how we will tell whether it works. From there, the work moves forward in increments that can be reviewed and used.
Not left until the end
Data quality, permissions, failure modes, operating cost and documentation are considered while the system is being built.
We review the starting point with the people who know the problem. Together we define what needs to change, who it is for and how we will tell whether it works.
Before building at scale, we check the data, integrations and decisions that could shape the whole project. If something is still unknown, we say so.
The work is divided into pieces that can be shown, tested and corrected. That lets us test decisions against real use without waiting until the end.
Before handover, we check deployment, access, alerts and what happens if something fails. The system has to be usable and maintainable day to day.
Sunny Data is an independent technology consultancy. The founder leads every project and stays involved in defining the problem, making the architectural decisions and building the solution.
The technical lead is the same person from the first conversation through to handover. There is no need to brief someone new as the work moves from one phase to the next.

During the project
The first conversation already covers the data, constraints, timescales and risks. The difficult parts are not left for later.
If there is more than one viable option, we set out what each one offers and what it demands. The team knows what was chosen and why.
We check decisions against the code, data and infrastructure. If something does not work as expected, we correct it early.
The team receives the repositories and documentation, and understands why the key decisions were made. It can maintain what has been built without depending on Sunny Data.
Bring us the outcome, the constraints and what is getting in the way. We will help you find a practical route forward.
